This invention relates to an improvement after the uppermost liquid compartment is in concentrators for liquids of the type in filled with hquid to be concentrated the furwhich the li uid to be concentrated is passed ther supplied liquid flows through the pipe over a suita le number of su rposed botk'to the next lower liquid compartment, and so a toms and heated in heating e ements lying so on.

laterally of the liquid container proper or "The operation is as follows:. vaporizing chamber and is thus concentrated The heating medium, for instance steam, by an uninterrupted working. The novelty enters the lower end of the heating chamber consists in forming the heating surface of at p and flows at high speed upwards along 05 each heating element-by one lower row of the heating elements while being uniformly wide heating tubes that are horizontally lodistributed'by the vertical guiding tongues f cated and a plurality of rowsof comparaand inclined baflles e and e and passing tively narrow heating tubes which are upthrough apertures gu, qu in the latter. wardly inclined toward the vaporizing The condensate formed runs down the in- 70 chamber and in communication with and clined baflies and drips from the lower baflle above said wide heating tubes, whereby the e at the .free bottom end thereof onto the efficiency of said concentrator is consideranext upperbaflle e underneath having for bly increased. a this pur ose an upturned free bottom end,

The accompanying drawings show the imthe con ensate belng hence led to the out- 75 proved concentrator by way of example in side through a common pipe 1', while the una preferred form of its construction: Fig. 1 condensed heating gases escape from the top is a side view thereof, partly in' section, of the heating chamber at a, where further while Figs. 2 and 3 are vertical sections on more, if desired, a safety valve 2 may be prothe lines IIII and IIIIII respectively vided 80 through the apparatus on lines IVIV of tinuously supplied at m enters the adjacent Figs. 1 and 3, with baflle plate 6 omitted for compartment of the uppermost subdivided sake of clearness. cup'h and passes, for its bein acted upon The improved concentrator has a plurality and boiled b the heating me ium flowing 86 of, for instance five, superposed heating elethrough the eating chamber, in a continuments consisting each of one row of'wide ous current first through the wide tubes a heating tubes a that are horizontally lo-' in rearward direction and-then through the cated and a plurality of rows of comparaheader 1 and the narrow tubes 6 in forward tively narrow heating tubes 6 upwardly indirection back to the cup h. The liquid fur- 90 clined toward the vaporizing chamber 9 and ther supplied at m causes part of the conin communication'wlth and above said wide tents in the cup k to flow through the header heating tubes. Said heating elements are I to the adjacent compartment of the subenclosed by a common heating case (1 havdivided cup, and so on, until it escapes from ing inclined baflies e and 0 respectively the last compartment of the cup through 95 above and below the bank of narrow heating the overflow pipe is into the next cu undertubes and vertical guiding tongues f fora neath, through which it flows in t e same uniform distribution of the heating medium way above-described.
